In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with the accompanying drawing embodiment that develops simultaneously, the present invention is described in detail.
Main thought of the present invention is: utilize multilink bundling technology, a distributed apparatus is divided into two virtual units in logic, by bandwidth mean allocation to two virtual unit of bundle link, substep is upgraded to two virtual units, in the process of upgrading, has retained to greatest extent service traffics.
In fact, multilink bundling technology is that a kind of interface by multiple encapsulation same link layer protocols is bundled into together, forms the technology of a data link in logic.Multilink bundling mainly contains following three effects:
A, flow load sharing: in/out flow can be shared between multiple member interfaces;
B, increase bandwidth, the bandwidth of multilink bundling interface is the summation of each available member's interface bandwidth.
C, raising connection reliability: when certain member interface breaks down, flow can automatically switch on other available member interfaces, thereby improves the connection reliability of whole bundle link.
In technical scheme of the present invention, the distributed dual master control network equipment need to be supported multilink bundling technology, if can not support multilink bundling technology, distributed dual-master control network equipment software updating method still adopts the method for prior art to realize.In the following examples, suppose distributed dual master control network equipment support multilink bundling technology, all business boards wherein form a data link in logic by multilink bundling.
Referring to Fig. 1, Fig. 1 is that the present invention realizes distributed dual-master control network equipment software updating method process flow diagram; Mainly comprise the following steps:
Here, the method that the distributed dual master control network equipment is divided into the first logical device and the second logical device is: all business boards in the dual master control network equipment are divided into the first business board group and the second business board group, the logical device of main control board and the first business board group composition is recorded as to the first logical device, the logical device of slave control board and the second business board group composition is recorded as to the second logical device.
In actual applications, the method that all business boards in the dual master control network equipment is divided into the first business board group and the second business board group can be: by managerial personnel according to the bandwidth of the work of all business boards (UP) interface, adopt artificial mode of specifying to divide into groups to all business boards, the bandwidth that makes the bandwidth of all UP interfaces in the first business board group in all bundle links and equal all UP interfaces in the second business board group as far as possible with; Or adopt simple algorithm to divide into groups to all business boards according to the bandwidth of the UP interface of all business boards, simple algorithm described here is the problem of specific implementation, a for example small routine, can make the bandwidth of all UP interfaces in the first business board group in all bundle links and equal as far as possible all UP interfaces in the second business board group bandwidth and.Here the bandwidth of all UP interfaces in the first business board group and equal as far as possible all UP interfaces in the second business board group bandwidth and, be in order the bandwidth of all bundle links to be tried one's best to mean allocation in the first logical device and the second logical device.
Here, the second logical device restarts carries out software upgrading and comprises: the main control board that in the reserved memory of all business boards, record starts next time in the second business board group is former slave control board, record upgrading mark in the reserved memory of former slave control board, in the second logical device, in the reserved memory of all veneers, record in the second logical device the slot number of every other veneer except self, the next startup file that former slave control board is set is software upgrading version file, restarts the second logical device; Described veneer comprises all business boards in former slave control board and the second business board group.
In actual applications, after the second logical device restarts and carries out software upgrading, closing all business interfaces in the second logical device also needs to set up before the communication link between all veneers in the second logical device.
Here, the first logical device starts to restart and comprises: it is software upgrading version file that former main control board startup file next time is set, and restarts the first logical device.
In actual applications, in the process that the first logical device restarts, former main control board carries out software upgrading as new slave control board load software upgrades version from the storage medium of self, join the second logical device, all business boards in the first business board group are also that new main control board load software upgrades version carries out software upgrading from former slave control board, add the second logical device, the first logical device and the second logical device are again as an equipment job.
The present invention is described in detail to lift preferred embodiment below.
Referring to Fig. 2, Fig. 2 is that preferred embodiment of the present invention realizes distributed dual-master control network equipment software updating method process flow diagram, and the method comprises the following steps:
In this step, the described main control board that in the reserved memory of all business boards, record starts next time in the second business board group is that the method for current slave control board is: the slot number that the slot number of the main control board that in the reserved memory of all business boards, record starts next time in the second logical device is current slave control board.The main control board of record startup next time in the reserved memory of all business boards in the second business board group, for when start next time, the main control board that business board started according to the next time of recording in self reserved memory starts from main control board load software upgrades version, while starting, former slave control board will start as main control board next time.
In the reserved memory of master control borad, recording a upgrading mark, is mainly for when former slave control board restarts, and can also in normal work, again as slave control board, not start because of former main control board, but start as main control board; In addition, also need to be in the second logical device record in the second logical device the slot number of every other veneer except self in the reserved memory record of all veneers, described veneer comprises: all business boards in former slave control board and the second business board group.
Step 201,202, what mainly complete is the preliminary work before distributed dual master control upgrading network equipment, and in this process, the service traffics of equipment are still front identical with preparation upgrading, and all business boards are subject to the control of main control board, carry out message repeating.
In this step, after the next startup file of slave control board is set, using the second logical device being formed by slave control board and the second business board group as one independently equipment restart, also start all veneers in the second logical device.
After slave control board in the second logical device is restarted, the slot number of main control board when all business boards in the second logical device started according to the next time of recording in reserved memory, using slave control board as new main control board, from new main control board load software upgrades version, start, and complete the reciprocal processes such as registration, this is same as the prior art, repeats no more.
After the second logical device restarts, according to multilink bundling technology, in the second logical device, the service traffics of all business boards automatically switch in the business board in the first logical device.
All veneers in step 204, the second logical device are set up communication link according to the every other veneer except self in the slot number and the second logical device that record in reserved memory separately.
In this step, because before all veneers of restarting in the second logical device, in the reserved memory of all veneers, recorded in the second logical device the slot number of every other veneer except self, therefore, here, according to other veneers in slot number and second logical device of record, set up communication between plates link, former slave control board be can't see former main control board as new main control board, and the first logical device and the second logical device are independent mutually.
After business board in step 205, the second logical device has started, close business interfaces all in the second logical device.
Before the distributed dual master control network equipment is divided into the first logical device and the second logical device, all business boards have identical configuration, and when dividing after logical device, the configuration of business board is still with originally identical, therefore, after the second logical device has been restarted, as with the second separate logical device of the first logical device in business board likely can with the first logical device in business board produce service conflict, the address conflict for example causing because configuring identical MAC Address, therefore, here, simply the business interface of all business boards in the second logical device is closed, to avoid conflict, after the first logical device, recover again business interface restarting.
In this step, former main control board startup file next time is set, restart the first logical device, also restart all veneers in the first logical device, all veneers in first logical device here comprise: all business boards in former main control board and the first logical device in the first logical device.
Pent business interface in step 207, recovery the second logical device, removes the data that record in the reserved memory of all veneers in the second logical device.
In this step, by after all single board startings in the first logical device, recover pent business interface in the second logical device at once, and then recover service traffics, former slave control board becomes the new main control board of the distributed dual master control network equipment.Removing the data that record in the reserved memory of all veneers in the second logical device comprises: remove in the second logical device recording in the reserved memory of all veneers in the slot number, the second logical device of the main control board starting next time of recording in the reserved memory of all business boards in the upgrading mark that records in the reserved memory of former slave control board, the second logical device the slot number of other all veneers except self.
Here, restart in the first logical device after all veneers carry out software upgrading, recover in the second logical device before pent business interface, business board in the first logical device and the second logical device all can not carry out message repeating, therefore, have very of short duration service traffics and interrupt, but with respect to whole escalation process, this break period is negligible.
After step 208, former main control board restart and have upgraded, add the second logical device to become new slave control board, after starting, all business boards in the first logical device from the former slave control board load software upgrades version of the second logical device, add the second logical device.
Here, according to the principle of work of distributed dual master control network, in all single-board starting process in the first logical device, can find that new main control board is in work, therefore, when the former main control board in the first logical device starts, can automatically as new slave control board, start the former slave control board loading upgrading software version that all business boards in the first logical device also can be in trend the second logical device.After the first logic has restarted, former main control board, former slave control board and all business boards are again as an equipment job, and distributed dual master control equipment software upgrading completes.
It should be noted that, in above-mentioned technical scheme, all operation stepss can be by managerial personnel by the mode of input command, for example order relevant to dividing logical device, with device-dependent order of enable logic etc., control the dual master control network equipment complete.
Referring to Fig. 3, when Fig. 3 is the distributed dual master control upgrading network equipment shown in Fig. 2, logical device is divided schematic diagram.Before upgrading, main control board, slave control board, all business boards that represent with slot number move as an equipment.When needs carry out software upgrading to the distributed dual master control network equipment, the logical device that the distributed dual master control network equipment is carried out is divided into: the first business board group of primary main board, slot number 1,2 representatives is divided into the first logical device, the second business board group of slave control board and slot number 3,4 representatives is divided into the second logical device, the bandwidth that makes the bandwidth of all UP interfaces in the first business board group in all bundle links and equal all UP interfaces in the second business board group as far as possible with.
Referring to Fig. 4, Fig. 4 is service traffics schematic diagram in the distributed dual master control upgrading network equipment process shown in Fig. 2.
Before the T1 moment, do the grouping work before distributed dual master control upgrading network equipment, service traffics are unaffected, and maximum traffic flow can reach the bandwidth sum that all business boards of the first logical device and the second logical device can reach, and is equivalent to step 201,202; Here and the business board cited below maximum traffic flow that can reach refer to the max-forwards ability of business board, be also bandwidth.
The T1 moment, in the second logical device, all veneers restart, in T1 arrives the T2 time, all veneers in the second logical device restart upgrading, because all business boards in the second logical device start, service traffics are the maximum traffic flow that in the first logical device, all business boards can reach to the maximum, are equivalent to step 203,204;
The T2 moment, all single board startings in the second logical device complete, at T2, arrive the T3 time, in the first logical device, all veneers restart, because all veneers need to cut out all business interfaces in the second logical device before restarting in the first logical device, in the first logical device, all veneers need to recover the pent business interface in the second logical device at once after restarting, after in the first logical device, all veneers restart, recover in the second logical device before pent business interface, service traffics have of short duration interruption, but with respect to whole escalation process, this break period is negligible, be equivalent to step 205, 206, 207,
In T3 arrives the T4 time, all veneers in the first logical device restart and carry out software upgrading, all normal working of single board in the second logical device, service traffics maximum can reach the maximum traffic flow that in the second logical device, all business boards can reach, and is equivalent to step 208.
In the T4 moment, all veneers in the first logical device complete restarts upgrading, adds the second logical device, and now, maximum traffic flow is restored to the maximum traffic flow sum that all business boards of the first logical device and the second logical device can reach.
Therefore, if the first logical device is identical with the maximum traffic flow of the business board in the second logical device, in the process of upgrading, can keep 50% service traffics, if current service traffics be less than the distributed dual master control network equipment business transfer capability 50%,, in escalation process, current service traffics can not be subject to the impact of escalation process, can complete whole forwarding work.
